VessFire course 2026

We are pleased to announce upcoming courses in Trondheim and Kuala Lumpur this autumn.

27–28 OCTOBER 2026

10–11 NOVEMBER 2026

Petrell invites engineers and technical professionals to a two-day course covering the physics, engineering principles and practical use of VessFire for process depressurization and fire-response analysis.

The course combines theoretical understanding with demonstrations on selected test cases and refers to the fundamental principles outlined in ISO 23251:2020 / API 521 (2022).

  • Existing VessFire users who want a refresher
  • Engineers considering becoming VessFire users
  • Professionals interested in the physics of depressurization
  • Blowdown and flare-system fundamentals
  • Fire exposure, heat loads and low temperatures
  • Material response and acceptance criteria
  • Practical modelling and output review in VessFire
